Here are 3 ways to retrieve unique values from arrays in Javascript

The array.filter method which is a higher order function which means it takes a function as it's argument.

const someArray = ['😁', '💀', '💀', '💩', '💙', '😁', '💙'];

const getUniqueValues = (array) => (
  array.filter((currentValue, index, arr) => (
		arr.indexOf(currentValue) === index

Since Chrome apps are now being deprecated. Download postman from https://dl.pstmn.io/download/latest/linux

Although I highly recommend using a snap

sudo snap install postman
